Ammonia Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Atrazine Atrazine Concentrations for Cairo, Evansville, and Louisville in EXCEL format. Bacteria E.Coli and coliform bacteria information for Cincinnati, Evansville, Huntington, Louisville, Pittsburgh and Wheeling. Chlorides Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Clean Metals Current Clean Metals Data - Metal Data from the Ohio River. Cyanide Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Cyanide analyses are only conducted at eight of the upper-river sites during the months of January, March and November. During the warmer months cyanide quickly decompeses into ammonia and carbon dioxide and is rarely detected, and as such, is only analyzed during winter months. Electrofishing/Fish Electrofishing Access Database - Electrofishing is an active sampling method for obtaining a qualitative and quantitative sample of fish populations using electricity. Fish Tissue Fish Tissue EXCEL Files - ORSANCO collects fish and examines the tissue for the presence of certain chemicals that may be harmful when ingested by humans. Flows Ohio River Flow and Velocity Forecasts Macroinvertebrate Macroinvertebrates Access Database - ORSANCO uses these small water-dwelling organisms as indicators of water quality; some require good, clean water to survive and reproduce. Nitrate/Nitrite Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Nutrients/Algae Nutrients and Algae Access Database - Collection of data on algal composition and abundance at multiple Ohio River locations so that status and trends can be tracked for water utility companies. Organics Detection System Organics Detections System - The Organics Detection System is a cooperative effort involving water utilities and other major Ohio River water users to detect organic compounds in the river. Phenolics Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Published Data Data is available in our Publications Section, All Downloads are in PDF: Annual Report, Compact, Pollution Control Standards 2000, Quality Monitor, Biannual Assessment-(305b), and Protocol for Addressing Interstate Inconsistencies. Quality Monitor The Quality Monitor publication provides information about the water quality of the Ohio River and its major tributaries. Water quality data are collected through ORSANCO's monitoring programs, including: bimonthly and quarterly collection of samples by ORSANCO field personnel; dissolved metals sampling; bacteria sampling during the recreation season and Organics Detection System (ODS). Sampling sites are located on both the Ohio River main stem and lower reaches of major tributaries. Spills Ohio River Spill Reports. Must have authorization to view material.

Total Organic Carbon Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Total Phosphorus Analytical results of bimonthly samples collected from 31 locations on the Ohio River and its tributaries. In addition to the routine set of parameters collected bimonthly, quarterly analyses for eight total metals are performed on a rotating basis among stations. ORSANCO adopted dual criteria for several inorganic toxicants to protect against chronic (long term) and acute (short term) toxicity to aquatic life. Watershed Pollution Watershed Pollution Reduction - ORSANCO’s Watershed Pollutant Reduction Program was established in 1995 to investigate specific pollutants on a watershed basis. The program combines existing data with targeted monitoring activities to identify sources of these pollutants and develop control strategies Wet Weather Wet Weather: Cincinnati, Louisville, and Wheeling - Pollution of the Ohio River from urban areas is a significant problem. Previous ORSANCO studies have pinpointed elevated levels of bacteria from such sources as combined sewer overflows (CSOs) to be the pollution source most in need of attention. |
